Create a similar rollup

Make some load-from-disk function pointers optional in query vtables

For queries that never incremental-cache to disk, we can represent that fact with None (i.e. a null function pointer) in their vtables, and avoid having to generate stub functions that do nothing.

(There is no decrease in vtable size; we just go from 3/8 padding bytes to 4/8 padding bytes.)

There should be no change to compiler output.

Port `rustc_layout` to attribute parser

Fix flakyness issue with `tests/rustdoc-gui/globals.goml` test

Just realized that when the search input is wrong, sometime we don't even load the search index (which is logical). Since we want to check that the search index is loaded, turned the query into something that works.

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
